I have an '03 530i with 60k miles. I intend to replace the brake pads/rotors with Cool Carbons and Ate rotors.

I look at the bedding-in procedure for the Ates, and it says to go easy for 400 miles. Looking at the Cool Carbon instructions, I'm told to do a dozen 60 - 20 mph stops to build up friction material on the rotors, let cool down for a few minutes, then do it again.

Since these two things seem somewhat contradictory, does anyone have any real-world guidance? The car is used for mostly highway driving, but I'll be autocrossing it, too.

Thanks,
Brian
